I have missed load of these now, so sorry for backtracking.
It would be sharks for me, scared of the dark and things that go bump in the night.
I would hate to be a teenager for 40 years. My teen years were grim. I would want to be in reasonable health as a 200 year old though.I don't want to be sitting in a chair, dribbling, incontinent and babbling incoherently.
Jump off a cliff any day, I am scared silly about flying never mind jumping out the thing, no chance.
Bats and tarantulas, I will be honest and say, I could not do either. I hate both, so even if I was offered enormous wadges of cash I would not be able to do either. In fact I don't think I could even do it for the much wanted green card.!
Well maybe the tarantula thing, if I was covered from head to toe in in full fire fighting garb,an was very,very,very, drunk. No that would not work, if I was very drunk,I would be seeing double, so twice as many of the little critters.
